Simple Fact Families
This is a Big Maths term meaning a group of connected mathematical facts. Understanding fact families is really useful, especially when dealing with algebraic questions (where there is a missing number in the question). To illustrate this using a simple example, if you were asked 3 + ? = 10, you could work out the missing number by creating the fact family, ie 10 - 3 = 7 so 7 is the missing number because it fits into the fact family.
